We used Ricardo for our welcome reception and wedding in April 2014 in Playa Del Carmen.  From the moment we first emailed him, he was super responsive and professional.  He would literally respond to emails within minutes, while many of our other vendors took days to respond if they responded at all.  He was able to edit songs to our liking, used all the songs we asked him to play, and most of all, he kept the party going until 4AM.  He did a great job.  I would recommend him to anyone getting married in Cancun / Playa / surrounding area.
